WebHistones are proteins, found in the cell nucleus, on which DNA is wrapped around; they are epigenetic marks that play an important role in gene expression regulation. A common form of histone modification is histone methylation, in which one, two, or three methyl groups may be transferred to lysine. WebDec 11, 2009 · Here, we analyzed the effects of light on four histone modifications (acetylation and trimethylation of lysines 9 and 27 on histone H3: H3K9ac, H3K9me3, H3K27ac, and H3K27me3, respectively). Our genome-wide profiling of H3K9ac and H3K27ac revealed that these modifications are nontransposable element gene-specific.
